Will First Contact be through Alien Machines?

Britain's Astronomer Royal, Prof Lord Rees, says that if we were to make contact with extraterrestrials from outside our solar system, it would be with intelligent machines, rather than with organic aliens.

While addressing an audience at the Cheltenham Science Festival last week, Rees said that an incoming SETI-like signal would likely be from machines built by a previous extraterrestrial civilization, since machines would be more suited to the rigors of space travel, as opposed to their biological creators, who are likely to have died out long beforehand.
